New machine (Lenovo L14 Gen3). Full disk encryption using discrete partitions with the same password ("/", "/home", swap). On boot, the Lenovo logo flashes instantly and the prompt for the disk encryption key pops fast. At this point, ctr-alt-del is ignored. There is no time nor message to press F1 for bios config or F12 for boot menu.
dunno about your machine exactly but when searching google for lenovo L14 bios key there are endless articles about all kinds of lenovo machines and ways to enter the bios or uefi, and an article comes up for a gen 2 of that L14 but also with additional machine type model numbers or something. anyhow those articles mostly say, try the ENTER and or F1 key quickly during POST of bios/uefi. once you are past the bios or uefi stage there is no way to enter into bios uefi any more thats my knowledge at least. i have seen all kinds of other vendors that need happily tapping keys such as TAB, F1, F2, F9 or F10 F11 and so on mostly, but some react to ESC (hewlett packard) and so forth. sometimes its alsi futile to hopple on the keys like a madman, so its just a pain. as others have stated, try to add boot delay or similar functions called in your bios uefi settings etc. good luck
